Lesson 9

Objective

Recognize and generate equivalent fractions with larger units using visual models.

Anchor Tasks - Problem 1

a.   What fraction of the rectangle below is shaded?

b.   Laura says that $${{1\over4}}$$ of the model is shaded. Do you think she is correct? Explain why or why not by using the picture.

Anchor Tasks - Problem 2

A point is shown on the number line diagram below. 

Write three equivalent fractions that name this point. 

Anchor Tasks - Problem 3

Solve for the missing value.

a.   $${{8\over24}={\square\over6}}$$

b.   $${{32\over10}={16\over\square}}$$

Problem Set

Target Task - Problem 1

The model below represents one whole. 

Which fraction is equivalent to the one represented by the shaded part of the model?

A.   $${{1\over8}}$$

B.   $${{1\over4}}$$

C.   $${{1\over3}}$$

D.   $${{4\over3}}$$

Target Task - Problem 2

A point is shown on the number line diagram below. 

Write three equivalent fractions for the location of this point.

Target Task - Problem 3

Use the number line to explain how you know the fractions in #2 are equivalent.
